What's with Telerik Control Panel? I'm unable to open it since yesterday on two different machines getting "Failed to retrieve data from Telerik web service" error message:

Hello,

please deactivate and delete my Account .

Thank You.

Hi, sorry i am new to Web Applications and do not know all of the features inside the different versions yet.

I need a help here to estimate if i better should use the Telerik + ASP.Net Core (+ Razor Pages) or older ASP.Net MVC5 version.

 

I have 2 requirements  to solve.

 

1) creating a generic Grid. ( user should be able to select any tablename from sqlserver schema , and the structure is only known at RT. ) and this should be

     shown with CRUD operations on them.( grouping , paging not needed but sorting and filters )

     so ok there is an ExpandoObject Class which can give me a Runtime type and i found Telerik Grid could be bound against it but last issue very old 2011 was

     that there is a problem with Inserts/Update/Deletes.

2) A  Grid with a known model. ( But there are some features needed like grouping, maybe paging, aggregation and CRUD as well sorting and filtering ) .

 

So from your opinition may it better to choose Telerik Grid with   ASP.Net Core ( + Razor)  or ASP.Net MVC5

thanks a lot

.With the announcement from Microsoft that .Net Core 3 will support WPF: https://blogs.msdn.microsoft.com/dotnet/2018/05/07/net-core-3-and-support-for-windows-desktop-applications/

Can we get word from Telerik if they will invest resources into porting thier toolkits to this framework?

Hello everyone,

Telerik TV was our first initiative to provide educational and technical video content to our developer community.

It has been replaced by the more advanced Virtual Classroom, which was also recently revamped. The service is available to all licensed customers and we invite you to check it out here:

Not sure where to put this. When I write a new post, and have the caret at the end of the post, and press Shift+Ctrl+Left I select the last word.

• But if start typing then the space before the last word will also be deleted with the selection, which is not expected.
• If instead of typing I press Shift+Ctrl+Left again the selection will not expand to another word, but disappear altogether. The caret jumped from selection beginning to selection end. And if I press Shift+Ctrl+Left for the third time a new selection will appear, without the last word.
• But get this. If I don't raise the Left key in previous use case then selection will retain the last word. Caret will not jump.

If the caret is in the middle of the text and I repeat Shift+Ctrl+Left until the beginning of post, and continue repeating, then the caret will also jump from selection start to selection end and the selection will shrink with each key press. The expected behavior is for caret to not jump, and selection to remain the same.

But this only happens if I raise Left key at least once. Otherwise the selection remains unchanged while I hold Shift+Ctrl+Left.

Hi. Is it possible in Telerik Fiddler to configure the program rules to automatically replace certain values in the sent requests? For example, when sending a query "answer=do&variant_3=1", configure Fiddler to automatically change the value from 3=1 to 4=2 before sending it to the server?

I'm looking for experienced ASP.NET developer who lives in Oslo/Norway or is willing to relocate. We are using the Telerik asp.net controls (tree, tab, grid, splitter,...), and possibly will be using some of the WinForms ones too.

If you are interested, please contact me at: development(at)compello.no

Sorry for the misleading subject and it seems that I can't change it...

I have a CURRENT DevCraft license. But I would like to develop for an old version, the oldest I can download is 11.x.x.x and I need to download 9.x.x.x

Do current licenses cover OLD Versions?

Hi all, forgive for nagging, but as far as MVVM is concerned, the kendo UI documentation plainly pushes you away from any sort of declarative use of their controls.

There is not a single documentation page for any specific control, that illustrates declarative use. If you search for it, there is a single page tht deals with the issue with only generic info on it, and little or no regard for advanced use cases. For example ... how do I set the animation duration for a progress bar using declarative syntax ?

Right now the answer is "waste some time to try out all the different data-*** attributes you can think of, and all the kinds of values you can give them until you succeed"

I find that annoying [ to say the least ], but there is a more severe side-effect.

The junior programmer reading this documentation will NEVER spend additional time to try out stuff or even imagine that there is a declarative way of doing things. I've just finished porting to declarative a few hundred lines of code that were just there to initialize controls inside data-bound templates !  Meaning ... those junior devs will NEVER know what true MVVM is, and what it looks like.

And all that is the result of the wrong documentation. You guys should really think if you're competing with jQuery or Angular. And make it apparent too, because right now you're just pushing devs the wrong direction.

Sorry for the nagging, but I can't stand this anymore.
